Why we are doing this. This check-in helps us see what you already know and which math ideas we should practice more, so we can plan lessons that give you the instruction you need.
WARM-UP

The Order of Operations (PEMDAS)

Look at the letters in the acronym PEMDAS. Write the math word that each letter stands for (for example: "Add" or "Multiply").

1.P
2.E
3.M
4.D
5.A
6.S
Strategy — Say the acronym out loud, one letter at a time, and ask "what math action starts with that sound?" Fill in the letters you are sure of first, then come back to the ones that are left.
PART 1

Is it an Expression or an Equation?

Look for an equals sign (=). If it has one, it is an Equation. If it does not, it is an Expression. For the last two, write the math you hear.

1.2 + 3   (circle one):   Expression  |  Equation
2.4 = 9   (circle one):   Expression  |  Equation
3.7 - 5 = 2   (circle one):   Expression  |  Equation
4.8 - 1   (circle one):   Expression  |  Equation
5.10 = 5 + 5   (circle one):   Expression  |  Equation
6.6 + 4   (circle one):   Expression  |  Equation
7.5 × 2 = 10   (circle one):   Expression  |  Equation
8.9 ÷ 3   (circle one):   Expression  |  Equation
9."Six plus four equals ten." Write it as math:
10."Ten minus five." Write it as math:
Strategy — Before you decide, scan the line for an equals sign and circle it if you find one. That one symbol is the whole test — let it choose your answer.
PART 2

Using Numbers for Real Life

If you have money, write the number. If you owe money, put a minus sign in front. For temperature, you can draw or use a number line if you like.

1.You have $7.
2.You owe $5.
3.Your bank had $10. You spent $6. How much now?
4.It is 3 degrees below zero.
5.It is 5 degrees above zero.
6.You find $4.
7.Which is bigger: -2 or 1? (Use a number line if you want.)
8.Which is smaller: 3 or -5?
9.Maria owes $2 and then gets $5. What does she have now?
10.It was -4 degrees. Then it warmed up by 6 degrees. What is the new temperature?
Strategy — Decide the direction before the size: does the situation add to what you have (a plus) or take away (a minus)? Choose the sign first, then work with the number.
PART 3

Number Line Problems

Draw a number line if it helps. Show your thinking with marks or arrows.

1.Draw a number line and put -3, 0, and 4 on it.
2.Start at -2. Move 5 spaces right. Where do you land?
3.Put in order from smallest to biggest: -1, 2, -4.
4.Start at 6. Move 8 spaces left. Where do you land?
5.Draw zero. What is on the left and right of zero?
6.3 + 7. Use a number line if you want.
7.5 - 9. Use a number line if you want.
8.How far is it from -4 to 2 on a number line?
9.The temperature went from -3 to 4. How much did it change?
10.You start at 0 and lose 6 points. Where are you?
Strategy — Put zero in the middle first, then step one mark at a time: move right for more/warmer, left for less/colder. Count the jumps you make instead of guessing.
PART 4

Doing Steps in the Right Order

For each problem, find what to do first, second, and last. You can number your steps "1," "2," "3," or talk about them. Circle what you do first.

1.2 + 3 × 4
2.(5 + 2) × 3
3.4 × (2 + 3)
4.8 ÷ 2 + 5
5.6 + 2 × 3
6.(10 - 4) + 2
7.5 × 3 + 1
8.2² + 4
9.7 + (5 × 2)
10.Why do you think we have to do math steps in a special order?
Strategy — Look for grouping symbols (parentheses) and any multiply or divide before you touch an add or subtract. Circle the very first operation before you compute anything.
PART 5

Working With Letters (Variables)

Circle the letter — it is called a variable. If the question gives a number for the letter, use it to solve.

1.What is the variable in: x + 2 = 5?
2.Which number never changes in: x + 2 = 5?
3.If x = 4, what is x + 3?
4.If y = 2, what is 2y + 1?
5.Write a math problem with "n" for the number of apples.
6.Which sign means "sum" or "add"?
7.If a = 7, what is a - 3?
8.If b = 5, what is 3b + 2?
9.Write with math: "twice a number n, plus one."
10.A student has x shirts, then gets 2 more. Write the math.
Strategy — The variable is the letter that can change; the constant is the plain number that stays put. When a value is given for the letter, swap it in wherever you see the letter, then do the arithmetic.

💡 Remember

FOR MENTOR USE — READ BEFORE YOU BEGIN

How to run this diagnostic so it stays low-pressure and gives you useful information

1. What this check-in builds

It is a starting picture, not a score. Across six short sections — order of operations, expressions vs. equations, signed numbers in real life, the number line, step order, and variables — it shows which foundations are already solid and which need practice before College Algebra. Treat the result as a map for planning, never a grade.

2. Run it low-pressure

3. Using the Strategy nudges

Each part has a yellow Strategy box. Have the student try the part first, and read the box only if they stall. The nudges name a first step or method — "circle the equals sign," "put zero in the middle," "swap the number in for the letter" — and never give the answer or which option is right. If you help read a box aloud, read it as written; do not add the solution.

4. Supporting the student

5. Using results to plan lessons
